Log a glucose reading
To log a reading, open the Add tab, leave the segment on Glucose, tap the big Tap to enter field, type the number your meter shows in the unit shown beside it, and tap Save Glucose Reading. The field is empty every time you come to it — SugarPaws never pre-fills a reading, so a stray tap on Save cannot record a plausible number you never measured. The reading is saved the instant you tap (before the toast animates), timestamped now unless you changed the time, and the last-reading strip at the top updates.
The reading field
Section titled “The reading field”| mg/dL | mmol/L | |
|---|---|---|
| Keyboard | Decimal pad | Decimal pad |
| Recorded to | The whole number (105.6 → 106) | One decimal place (5.55 → 5.6) |
| Lowest recordable | 20 | 1.1 |
| Highest recordable | 999 | 55.5 |
The ceiling is deliberately high: pet meters read up to about 750 mg/dL and a
severely uncontrolled cat can exceed 600. A comma works as the decimal
separator (5,5), because that is what the keypad inserts in many regions.
Save Glucose Reading is grey and disabled while the field is empty. Once there is text it stays tappable even when the text is not a valid reading, so that tapping it can tell you why under the field instead of doing nothing:
| Message under the field | Cause |
|---|---|
| Enter a number in mg/dL. (or mmol/L) | Not a number — letters, or a value with both , and . in it, which is locale-ambiguous and rejected rather than guessed at |
| Readings below 20 mg/dL can’t be recorded. (1.1 mmol/L) | Below the floor |
| Readings above 999 mg/dL can’t be recorded. (55.5 mmol/L) | Above the ceiling |
Out-of-range input is rejected, never clamped — a mistyped 1500 does not quietly become 999. The message clears as soon as you start editing.
Time and notes
Section titled “Time and notes”- Time is a compact date-and-time picker pre-set to now. Leave it alone and the reading is stamped at the moment you tap Save (not the moment you opened the screen); change it and your chosen time is used instead. You cannot pick a time in the future. It resets to now after every save.
- Notes (Optional) is a free-text field, up to 500 characters
(anything longer is cut off as you type). Notes appear under the reading in
History, in the CSV
Notescolumn, and — truncated with an ellipsis to fit one line — in the PDF report.
Tap Done on the keyboard bar, or drag the form, to dismiss the keyboard. Switching to the Insulin segment and back keeps whatever you had typed.
”Check before saving” warnings
Section titled “”Check before saving” warnings”Before writing, SugarPaws checks the reading and, if anything is unusual, shows one dialog titled Check before saving listing every applicable warning, ending Double-check before saving. — with Save Anyway and Cancel. Two conditions can trigger it:
| Warning | When |
|---|---|
| You logged this same reading N minutes ago. | The most recent reading for this cat has the same value and its time is within 10 minutes of this one. A genuinely repeated measurement will differ by at least a point, so this catches a double-tap. |
| Value unit is outside the range a cat’s meter usually reads. | The reading is below 40 mg/dL (2.2 mmol/L) or above 500 mg/dL (27.8 mmol/L). It is still recordable — the app is asking you to look twice, not refusing. |
Both can appear together. Confirming one does not skip the other: a 700 mg/dL double-tap gets both lines in the same dialog.
What the saved reading looks like elsewhere
Section titled “What the saved reading looks like elsewhere”The value is stored in mg/dL whatever unit you type in (mmol/L × 18) and
converted back for display, so changing the unit later re-labels every reading
without altering it. In History the value is coloured and marked by its
position against the cat’s target range; the charts plot it as a red point;
the CSV carries it in both Value (mg/dL) and DisplayValue (your unit).
